The key concept is that the receiver can be in one of two different states or modes, and two of the 32 codes are reserved for putting it into one state or the other. 11111 puts it into "letters" mode ... WebThe LTRS character is 11111 in Baudot code. If you put the mandatory single Space start bit in front and the two Mark stop bits at the end it’s 01111111. At that is what you see in the oscilloscope. It was difficult for me set the scope so it could be shown exactly this way, but the diagram below shows it more clearly.
